Push and pull data transfer methods are two major strategies utilized by data communication systems. In a pull system, data transmission is initiated by a data receiver or client, essentially forming a request-response transmission model. To the contrary, a push system data transmission requests are initiated by the data publisher or server, wherein the data publisher sends notifications and/or data based on data availability. Exemplary applications include an operating system (OS), where the push model may be characterized as an interrupt-driven system and the pull model as a polled input/output (I/O) system, and a client/server system, where the pull model may be configured as an HTTP protocol and the push model as an HTTP push protocol.
